Run 3 will take physicists closer to a unified description of QCD phenomenology, from the microscopic level to the emergent bulk properties of the quark–gluon plasma. Alice Ohlson explains. Hot and ...

With a new measurement imminent, the Courier explores the experimental results and theoretical calculations used to predict ‘muon g-2’ – one of particle physics’ most precisely known quantities and ...

From targets to absorbers, beam-intercepting devices are vital to CERN’s accelerator complex. Marco Calviani describes the major upgrades taking place to prepare for the high-luminosity LHC, and the ...

The development at CERN of magnesium diboride cables and other advanced superconducting systems for the High-Luminosity LHC is also driving applications beyond fundamental research, describes Amalia ...

Explaining the bizarre pattern of fermion types and masses has led theorists to explore more complex symmetry groups than the Standard Model’s, with recent work suggesting that the “flavour scale” ...

Oliver James of DNEG, which produced the striking black hole in the film Interstellar, describes the science behind visual effects and the challenges in this fast-growing industry. Gargantua A variant ...
